METHOD AND DEVICE FOR GENERATING ENERGY DURING THE ROLLING OF A TYRE FITTED ON A RIM

摘要

A device (10; 110; 210; 310) for generating energy during the rolling of a tyre (2) includes at least one part (); 30; 203) which can move with respect to a rim (3) and engages with at least one spring (15; 33; 202) which keeps it in contact with a predetermined portion (16) of a bead (4) of the tyre (2); the portion of bead (16) exerts on the moving part (9; 30; 203) a contact pressure which varies cyclically during each revolution of the tyre (2) and induces forces on the moving part (9; 30; 203) which are capable of causing it to move with a reciprocating outward and return motion, in a predetermined direction, against the action of the spring (15; 33; 202).
